To mark the occasion, the hospital is opening its doors to the public with a Healthy Communities Day.
The event, from 10am to 2pm, will feature a range of activities including stands and displays showcasing local NHS services, voluntary groups and private care providers.
Emma Bagwell, matron, said: “The public can learn more about the wide range of health services on offer in the Seaton area, while the event will also present an excellent networking opportunity for the staff and organisations involved.
“We are thrilled by the response we’ve had and it is shaping up to be a very exciting day for Seaton Community Hospital.”
Trust specialists, including physiotherapists and speech and language therapists, will be on hand while nurses will carry out free blood pressure checks and other simple observations.
The League of Friends will have a stand and have kindly agreed to provide refreshments and other assistance.
They will be joined by the Lions Club, Rotary Club, Royal British Legion, St John Ambulance and Age UK as well as private care companies Home Instead, Courtesy Care, Bluebird Care and Axe Valley Care.
The RNIB will be promoting its Talking Books service, Devon and Cornwall Police will be offering advice on home safety, the Devon Freewheelers will be parading some of their emergency courier motorbikes and there will be stands dedicated to healthy eating and NHS recruitment.
At 1pm there will be a presentation to the Seaton Home Nursing Team, which was recently named the winner of the Healthcare Hero awards run by the Northern Devon Healthcare NHS Trust.
The public will also have the opportunity to sign up as a member of the Trust, which would give them a greater say in the running of health services in East Devon.
Building work on the hospital, in Valley View, started in 1987 and it was opened by the Duchess of Kent on 10 May 1988.
